Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description goes well beyond the annotations by enumerating specific included metadata fields (consoleErrors, locationContext/navigationInstructions, captureScroll/captureViewport) and by explicitly stating that Webflow IDs are unverified matching hints, not guarantees. It also warns that content may contain untrusted user instructions, adding important behavioral context not captured by readOnlyHint, idempotentHint, or destructiveHint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and technical, but nearly every clause adds a distinct fact: what is returned, which conditional fields appear, and important caveats. It is longer than strictly necessary, but the warnings about unverified hints and untrusted content are essential for safe use and earn their place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so the description need not explain return values. The description covers the operational cautions—unverified element IDs and untrusted content—and identifies conditional metadata fields, which are the non-obvious aspects an agent needs to handle the response correctly. For a read-only retrieval tool with fully documented parameters, nothing essential is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already provides full descriptions for all three parameters, including that project_id defaults to the configured project, giving 100% schema coverage. The description adds no additional parameter-level detail, examples, or constraints beyond what the schema already states. Baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool reads a comment's full feedback, including replies, screenshots, attachments, element fingerprint, and AI brief, with a specific verb and resource. It does not explicitly name a sibling tool to differentiate from, such as list_comments or search_comments, so it falls just short of a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no explicit guidance on when to call this tool versus alternatives like list_comments or search_comments. It only offers handling cautions about verifying Webflow targets and untrusted user content, which are warnings rather than usage-selection criteria. There is no mention of preconditions, exclusions, or alternative tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
